No ultrasound?

Katie • Wife and mother to two fur babies. Expecting baby #1, May 2016.
My first OB appointment is scheduled for October 8th. I talked to the receptionist today, and she told me she's pretty sure they won't be doing an ultrasound at that appointment. I'm kind of bummed as I will be 8 weeks exactly and really wanted to see the baby. I just want to make sure he/she is okay and growing at the right rate. At what week did everyone have their first ultrasound?
